Effect of different chemicals and additives used in producing
polyester foam was investigated. Reference samples were produced from polyol,
toluene di isocyanate (TDI), amine stannous octoate distil water, and silicone
oil using laboratory mix formulation based on 500 g
polyether based polyol. Other samples were produced by consecutively
varying the content of all the additives with the exception of polyol. Standard
sample dimensions for density test, indentation test, compression set test,
tensile strength and elongation tests were produced from the samples. The
various tests were carried out on the samples using the ASTM-D3574 standards.
It was observed that the degree of indentation affects the value of indentation
hardness and increasing the percentage content of TDI results in acceptable
compression set value for the polyester samples. It was concluded that Holding
all other parameters constant, reducing the water content and increasing the
TDI content will yield polyester foam of optimum properties.
